ok, my main guess behind thinking about a tablet would be precision, I've been finding (playing around with sketchup so far) that I have to crank the settings on my mouse WAYYY down to be able to get any real decent control over positioning/placement etc of objects
program lists that are primarily used in the course I'm going into...
AutoCAD, REVIT, sketchup, Inventor, and a few others that arnt listed on the website, lol
